I have configured my Mac DNS with cloudflare DNSs - ipv4 and ipv6 - I am in trying to access this website - bpinet.pt - and all browsers Safari, Firefox, Chrome says it can reach that that.
When I remove those DNSs and put the internet provider default ones it work fine.
Why? This is happening since November 1st.
